Figure shown a \(DC\) voltage regulator circuit, with a Zener diode of breakdown voltage \(= 6\,V\). If the unregulated input voltage varies between \(10\, V\) to \(16\, V\), then what is the maximum Zener current ?.......\(mA\)
- A \(2.5\)
- B \(3.5\)
- C \(7.5\)
- D \(1.5\)
Answer & Solution
Correct Answer
(B) \(3.5\)
Step-by-step Solution
Detailed explanation
Maximum current will flow from zener if input voltage is maximum. When zener diode works in breakdown state, voltage across the zener will remain same. \(\therefore \) \({V_{{\text{across}}}}4{\mkern 1mu} K\Omega = 6{\text{V}}\) \(\therefore \) Current through…
